How many liters are in a gram?
One litre of water has a mass of almost exactly one kilogram (1000 gram). So, 1 gram is equivalent to 0.001 litre. 1 litre of chemically pure water has a mass of 1 kg at 277.13 K (3.98 °C or 39.164 °F), at which point the pure water occupies the minimum volume per mass.
gram = weight litre = volume no formula. not the same unit of measure. all depends on what you have a gram of or what you have a litre of... a litre of mercury will weigh many more grams than a litre of water... a gram of Mercury will occupy less of a litre then a gram of water... so there is no answer to your question. need more info.
The two cannot be directly converted - as it depends on what you measure (in regards to the mili liters part. This is because liters is a "spacial" measurement (ie. how much does space does it use) and mili gram is a weight measurement - and even though f.ex. sand and milk can both be measured in litres - 1 litre of milk would NOT weigh the same as 1 litre of sand, and thus…
Gram is a unit for measuring mass. Liter is a unit of volume. If you know the density of the material you can answer that question. For example, 500 grams of air would occupy many more liters than 500 grams of lead, because lead is much more dense than air. Without knowing what you have 500 grams of, it is impossible to say how many liters it would occupy.
